But it's not supposed to taste like an actual banana, but a Tokyo Banana, which is completely different (very little resemblance at all, really). Have you ever HAD a Tokyo Banana?

Nope. 😂 More of a sable girl when it comes to Tokyo omiyage, so I'll have to leave it to others as to whether it's a good representation of a Tokyo Banana. For me, it was just unpleasant and not worth the time spent queuing in the basement of Tokyo Station.
